cc.RenderTexture.saveToFile runs async and no callback

[emfox]

RenderTexture.setPosition(cc.p(winSize.width / 2, winSize.height / 2));
RenderTexture.beginWithClear(255, 255, 255, 0.0);
cc.director.getRunningScene().visit();
RenderTexture.end();
var imgPath = jsb.fileUtils.getWritablePath();
var result = RenderTexture.saveToFile(fileName, cc.IMAGE_FORMAT_PNG);
if (result) {
    imgPath += fileName;
        open_img(imgPath); // open_img a function to open file, but it say file not found!!!
    }

please add finish callback for it.
